First, coal-fired heating - heating costs are not low
Energy is sorted from low to high according to market prices as 1 coal, 2 electricity, 3 gas, and 4 oil. Although the coal price is the lowest, the heating costs paid by the common people are not low. This is mainly due to the low utilization of thermal energy of coal and the large heat loss of pipelines, together with the operation and maintenance costs of boilers, pipelines, labor and electricity, etc. Every square meter to the people feels higher.
Taking residential housing as an example, heating companies still suffer from high heat charges despite the high cost of heating. In some areas, the government has had to make huge investments to cover up heating in order to resolve contradictions. In addition, the heating of coal brings warmth to the city, and it also causes great pollution. It produces a lot of waste gas, waste water, waste residue, and takes up a lot of valuable land. Many cities have now started killing small boilers below 10 tons. The energy structure for heating has also shifted from coal to clean energy such as electricity, wind, solar, and natural gas.
High price, use safety
Gas fuel heating is the direct use of the heat generated by the combustion of natural gas and petroleum. This heating method currently includes a household gas stove for one household, a small gas-fired and oil-fired boiler for a building or a residential area, and large-scale heating. Regional heating gas and oil-fired boilers.
First of all, from a safety point of view, for the fuel heating users of households, problems such as the purchase, transportation, and storage of fuel cannot be solved. For gas users who have separate household heating systems, they can use pipes and gas storage tanks to enter the home. However, heating involves thousands of households in a wide area. The quality of personnel is uneven, and old and weak, sick and disabled need heating. This is to gas heating equipment. The safety requirements are very high, and all kinds of accidents need to be prevented. As far as gas and liquefied gas are used now, they are used in ignition and cooking. Fires, explosions, and conflicts are frequently observed each year, causing people to lack security. In particular, there are many high-rise buildings in the city, and the population density is high. Therefore, it is prudent to use single-burner gas stoves for heating.
Second, although fuel and gas furnaces have automatic alarm and shutdown devices, electronic equipment cannot be 100% reliable. If the leakage point is not in the detection zone or the concentration of leakage leaks at the detection point due to wind and other factors, the alarm shutdown standard cannot be met. And power system failures can have serious consequences.
Third, the fuel and gas furnace heating circuit is a closed system. Although the equipment has a temperature and pressure detection system, there are also reliability problems. Domestic gas and oil stoves require a lot of oxygen to work. We close doors and windows for thermal insulation and it will compete with us for limited oxygen in the room.
Fourth, the heating price is higher, and Beijing Gas Heating has a heating period of 30 yuan per square meter, which is 40% higher than electricity. Take a gas station in Shenyang as an example: The building area is 180 square meters, geothermal heating using oil furnace, a heating period of about 15,000 yuan oil, an average of 83 yuan per square meter (5.2 times the electric heating), but not Always burn, room temperature is about 12-13 degrees. It can be seen that the cost of gas heating is slightly higher, and the cost of oil heating is unacceptable.
Nearly 30% of Central Heating Festival Fee
Electric heating is a kind of high-quality, comfortable and environment-friendly heating method that converts clean electric energy into heat energy. After long-term practical application, it has been proved that it has superiority that many other heating methods cannot match. It has been recognized by more and more users worldwide. And accept.
First of all, electric heating is conducive to the country's environmental protection, energy conservation, land and water conservation, has a role in filling the valley of the national grid, and make the grid more safe and reliable operation. According to relevant sources, the peak-to-valley ratio of China's power grid is about 0.54, so the country can make full use of the resources of Gudian section to achieve energy saving and income increase without investing.
Second, electric heating is conducive to real estate developers to reduce costs: to reduce the amount of land, reduce heating costs.
Third, electric heating helps to reduce the cost of purchasing and heating costs, and provides flexible heating. Take electric heating as an example, the system is equipped with intelligent thermostats, and the people can realize heating on demand. When the room is temporarily unoccupied (for business reasons, etc.), it is possible to set up low-temperature heating or programmed valley sections to maintain heating. Room temperature, ready to stay. When the heating is stopped due to a power outage or the like, the room can be kept warm for a longer period of time. The room temperature fluctuates within 1.5 degrees within 24 hours, and the temperature is constant and comfortable. In the application of energy-saving buildings, when the room temperature is maintained at around 18 degrees, the central heating of the same period of each heating period can save 25-30% of the cost.
Fourth, electric heating is conducive to the collection of heating costs, measurement is accurate and non-controversial, how much heat to pay is conducive to building a harmonious society.
Fifth, electric heating is conducive to heating in urban non-concentrated heating districts, suburban areas, the Yellow River Basin, the Yangtze River Valley, and decentralized residential users in rural areas.
In summary, electric heating is the heating method that best meets the heating needs of the people. Now the country advocates clean electricity, which has emerged from wind power generation, solar power generation, hydropower stations, tides, nuclear power plants, and biogas power generation. These are clean energy sources. When the stream flows into the Yangtze River, all rivers will enter the sea. The last benefit will be electric heating. The future of electric heating is promising!
Obviously, a single warmth is far from enough, and people need a heating system that combines science, safety, environmental protection, economy, convenience, comfort, and energy saving. Then what kind of heating methods can be used to meet the needs of the people, such as coal-fired heating, gas fuel heating, and electric heating?
